Ka-chow! A simple irregular 2D lattice model of lightning [PDF]

open access: yesarXiv
A model of lightning that captures the propagation of lightning channels on an irregular lattice is developed. The irregular lattice allows us to capture large two-dimensional systems (2 km x 2 km), while allowing grid refinement (on the order of cm) near areas of interest.

Lightning Does Not Strike Twice: Robust MDPs with Coupled Uncertainty [PDF]

open access: yesarXiv, 2012
We consider Markov decision processes under parameter uncertainty. Previous studies all restrict to the case that uncertainties among different states are uncoupled, which leads to conservative solutions. In contrast, we introduce an intuitive concept, termed "Lightning Does not Strike Twice," to model coupled uncertain parameters.

Lightning-strike induced acute injury: A case report

open access: yesNigerian Journal of Paediatrics
Lightning strike injury is a rare but a devastating lifethreatening condition affecting virtually all tissues and solid organs of the body. This can be attributed to the various energy transmission mechanisms from lightning strikes.

Can Bayesian Networks Improve Ground-Strike Point Classification?

open access: yesAtmosphere
Studying cloud-to-ground lightning strokes and ground-strike points provides an alternative method of lightning mapping for lightning risk assessment. Various k-means algorithms have been used to verify the ground-strike points from lightning locating ...

Ball Lightning as a Self-organized Complexity [PDF]

open access: yesarXiv, 2007
The ball lightning phenomenon is explained in the frame of a self-organization scenario suggested by experiments performed on the spontaneously generated complex spherical space charge configuration in plasma. Originated in a hot plasma, suddenly created in a point where a lightning flash strikes the Earth surface, the ball lightning appearance proves ...
